| A 
				cordon was put in place along the seafront earlier on Sunday and 
				people were advised to shut all windows and doors or stay away 
				from the area.
 Sussex Police later said all the cordons had been lifted and the 
				seafront was open as usual.
 
 Two people were checked at hospital before being discharged and 
				advised to go home, wash their clothes and have a shower, police 
				said.
 
 An investigation into the incident was ongoing, police said, and 
				a number of lines of enquiry were being followed up.
 
 In August 2017 up to 50 people at the coast near Eastbourne, 
				about 60 km from Worthing, suffered irritation to their eyes and 
				throats from an unidentified chemical haze.
